So you answered my A or B question yes, but with your explanation I think you're saying A. If so:

Catcher drops strike three which hits the backstop hard and then hits the runner who a) has not had time to move. B) Has taken a couple steps toward first
In either case the ball hitting the runner prevents the charging pitcher from easily fielding the ball for an easy putout of the runner

Interference in B, the act was moving into the path of the ball, it interfered with a play on the runner
No Interference in A, the BR did not commit an act.

Is that correct?
